Quick answer：

Rubble stone paving is a method of laying stones with irregular shapes, often used for walkways or decorative purposes. A 'tree map' in this context likely refers to a visual representation or diagram of a tree, possibly showing the distribution or arrangement of the paving stones around trees or within a landscape. This type of map can be used for garden design or urban planning, showing the spatial relationship between trees and paving.
